Assessment of a potential storage site for carbon dioxide: A case study, southeast Queensland, Australia

Geoengineering and Economic Assessment of a Potential Carbon Capture and Storage Site in Southeast Queensland, Australia

“…A "maximum allowable injection pressure" has to be determined so as to preserve seal integrity (Streit and Hillis 2002;Rutqvist et al 2007). The maximum allowable CO 2 injection pressure is defi ned as a percentage of the fracture pressure [70 and 90% were used in Sayers et al (2006a)]. The higher the fracture pressure, the higher are the CO 2 injection rates.…”

“…A fl uvial meandering system is most representative of the Showgrounds sandstone reservoir modeled in the western part of the reservoir. The porosity-permeability ranges between 100 and 1,000 md-the upper end value was used by Sayers et al (2006a) in the modeling. Lower permeabilities can, however, apply occasionally.…”

“…The top of the reservoir rises 800 m from east-to-west and although the formation thickness varies from 3 to 17 m, a constant average reservoir thickness of 7 m is used in the modeling. A detailed geological description of the reservoir model was reported in Sayers et al (2006a). Analytical aquifers proposed by Carter and Tracey (1960) were used to represent the formations that surround the model area.…”

“…A multidisciplinary study has recently identified the onshore Bowen basin as having potential for geological storage of CO 2 (Sayers et al 2006a). In that paper, geological containment and injectivity and reservoir engineering simulation sensitivities showed that a target injection rate of 1.2 Mt CO 2 /yr over a 25-year project life span could be achieved (i.e., equivalent to injecting the emissions from a 400 MW gas based power station).…”

Screening and selection criteria, and characterisation techniques for the geological sequestration of carbon dioxide (CO2)

“…Environmental Geosciences has published two special issues in 2006 (numbers 2 and 3 of volume 13) and Environmental Geology has published a special issue in June 2008 (volume 54, number 8) devoted to the subject of site characterisation. Worth mentioning are the papers describing site-specific cases of site characterisation in North america at the Frio, Mountaineer and Tea Pot Dome sites hovorka et al, 2006;Lucier et al, 2006;chiaramonte et al, 2008;Doughty et al, 2008;Lucier and Zoback, 2008), in Europe (Förster et al, 2006;Meyer et al, 2008) and australia (Sayers et al, 2006;Gibson-Poole et al, 2008). Several papers of interest have been published in the International Journal of Greenhouse Gas Control.…”
